Title: Signal apparatus for transmitting the position of indicating apparatus
IPC: G08C19/02
Filed: 1938-01-31
Abstract: 514,364. Magnetic switches; selective signalling systems. QUAAK, A. J., and ROEBERS, P. J. Jan. 31, 1938, Nos. 3042 and 3043. Void. Convention dates, Feb. 2, 1937, and March 24, 1937. [Class 38 (v)] [Also in Group XXXVIII] When a member of magnetic material 12, which may be attached to the spindle of an indicating instrument, is moved into the air gap between the core 14 and the armature 13 of a relay having a constantly energized winding, the magnetic force becomes strong enough to attract the armature and operate contact springs The same magnetic member or rider may operate a number of relays in succession by passing through their air gaps, the relays being arranged, for example, in a circle. Fig. 2 shows three such relays A1, B1, Cl, adapted to send impulses to lines 1, 2, 3 and associated with auxiliary relays P, Q, R which serve to break the circuit to the control relays A1, B1, C1 after these have operated, thereby releasing the rider 12 so that it may move on easily to the next relay. For example, movement of the rider into the air gap of relay B1 will cause the closing of contact b4 in a controlled circuit and also the closing of a contact b1 causing the energization of relay Q which thereupon opens the circuit to B1 at q2 and closes a maintaining circuit for itself at q1. The de-energization of B1 opens contact b4 so that only an impulse will have been given to line 2. The maintaining circuit for Q will be broken at a2 or c3 when the rider moves to A1 or C1 respectively. The Specification also describes, Fig. 1 (not shown), a system for transmitting the indications of an apparatus to a distance, the apparatus having a set of three contacts controlled by the apparatus and controlling in their turn a relay group which controls a step by step indicator at the receiving station advancing this or setting it back.

Title: Improvements in the manufacture and production of emulsions of diolefines
IPC: C09K23/00
Filed: 1928-06-01
Abstract: 318,296. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). June 1, 1928. Divided on 312,201, [Class 2 (iii), Dyes &c.]. Emulsions, making.-Aqueous emulsions of diolefines are prepared by dissolving, in the diolefines and the water respectively, substances which react to form emulsifying agents and mixing the solutions so prepared. For example a solution, in a diolefine, of a fatty acid such as oleic, linoleic or ricinoleic acid or a resin acid is mixed with an aqueous solution of an organic or inorganic base, preferably ammonia. The diolefines are subsequently polymerized in the emulsion to form a svnthetic latex. Substances assisting polymerization or promoting subsequent vulcanisation or plasticizing or stabilizing agents may be added to the constituent solutions or to the emulsified product : such substances include oxidizing agents such as benzoyl peroxide with or without substances such as cobalt oleate or manganese cinnamate, proteins, pectins, natural or artificial resins and oils. An example of the process is as follows :-a solution, in 400 parts of B-methyl butadiene, of 5 parts benzoyl peroxide, 0.5 parts cobalt oleate, 12.6 parts olein, 4 parts piperidine piperidyldithiocarbamate and 10 parts linseed oil is added, with agitation, to 500 parts of 0.5 per cent aqueous ammonia containing 10 parts trisodium phosphate, 25 parts of a 5 per cent glue solution and 5 parts of a 10 per cent solution of hydrogen peroxide. The emulsion, on standing or moderate heating, polymerizes to a latex and may be coagulated to form a synthetic rubber.

Title: Improvements in cathode ray oscillographs
IPC: H03K4/16
Filed: 1924-02-11
Abstract: 235,254. Appleton, E. V., Herd, J. F., and Watt, R. A. W. Feb. 11, 1924. Electrostatic meters. - In a cathode-ray oscillograph. a time base which is sensibly linear and unidirectional is produced by means of an electromotive force varying at a controlled and uniform rate in one direction. An oscillating circuit C tuned to a high frequency, for example 3000 kilocycles, is connected in the anode circuit FA of a triode AGF. A reaction coil R is coupled to this circuit so as to produce oscillations. A condenser C is connected between the coil Rand the negative limb of the filament F, and across this condenser is connected a. diode D, which may be a triode of which the grid and plate are connected together. The filament current of the diode may be controlled by a rheostat P, and the saturation of the diode may be controlled by adjustment of a battery B, whereby the linearity of the time scale may be improved. The electromotive force across the condenser C is applied to one pair of plates of the cathode-ray oscillograph the conductivity of the saturated diode being preferably much greater than that between the plates of the oscillograph. With suitable adjustments the system oscillates in trains of oscillations. During each train the grid G rapidly becomes negatively charged, and at the end of each train the grid charge leaks at a uniform rate through the saturated diode D until the next train of oscillations occurs. The time of this leak is determined by the capacity of the condenser C and by the electron emission in the diode D. The ratio of the time of uniform leakage to that during which high-frequency oscillations takes place may be increased by increasing the temperature of the filament F of the triode. Specifications 221.338 and 223,368 are referred to.
